* Remove `make updatedeps` from Travis build. We'll follow up with more specific plans around dependency updating in subsequent PRs. * Update all `make` targets to set `GO15VENDOREXPERIMENT=1` and to filter out `/vendor/` from `./...` where appropriate. * Temporarily remove `vet` from the `make test` target until we can figure out how to get it to not vet `vendor/`. (Initial experimentation failed to yield the proper incantation.) Everything is pinned to current master, with the exception of: * Azure/azure-sdk-for-go which is pinned before the breaking change today * aws/aws-sdk-go which is pinned to the most recent tag The documentation still needs to be updated, which we can do in a follow up PR. The goal here is to unblock release. |

logutils
logutils is a Go package that augments the standard library "log" package to make logging a bit more modern, without fragmenting the Go ecosystem with new logging packages.
The simplest thing that could possibly work
Presumably your application already uses the default log package. To switch, you'll want your code to look like the following:
package main
import (
"log"
"os"
"github.com/hashicorp/logutils"
)
func main() {
filter := &logutils.LevelFilter{
Levels: []logutils.LogLevel{"DEBUG", "WARN", "ERROR"},
MinLevel: logutils.LogLevel("WARN"),
Writer: os.Stderr,
}
log.SetOutput(filter)
log.Print("[DEBUG] Debugging") // this will not print
log.Print("[WARN] Warning") // this will
log.Print("[ERROR] Erring") // and so will this
log.Print("Message I haven't updated") // and so will this
}
This logs to standard error exactly like go's standard logger. Any log messages you haven't converted to have a level will continue to print as before.
